Hi all,

I have got a question about subclass declaration scopes. The thing is we
will be sending the Controller IP to Aruba APs using Option 43.

The recommended configuration of Aruba for this is like the following:

option serverip code 43 = ip-address;
class "vendor-class" {
      match option vendor-class-identifier;
}
.
.
.
subnet 10.200.10.0 netmask 255.255.255.0 {
   default-lease-time 200;
   max-lease-time 200;
   option routers 10.200.10.1;

   subclass "vendor-class" "ArubaAP" {
      option vendor-class-identifier "ArubaAP";
      option serverip 10.200.10.10;
   }

   range 10.200.10.200 10.200.10.252;
}

As you can see in the example the subclass declaration is in the subnet.

I know that class declarations are global, but what about subclass
declarations? Are they global as well? If I have another subnet with the
same subclass name inside but with different serverip or router, would it
work correctly? Or what would you recommend for configuring Option 43 for
Aruba APs on different subnets with different controller ip?

Thank you so much in advance.
Alp
